You get what you pay for. The computer itself is nice, sensors not so much. Ordered the cadence/speed sensor with the computer. Just doesn't work with the geometry of a modern bike. There is simply no way it can be positioned to pick up magnets from both the wheel and the crank. Pitched it and ordered ANT+ sensors. Cadence sensor paired no problem. When pairing speed sensor, computer thinks it is a heart rate sensor. Can't figure out how to unpair it and try again. If I had it to do over again, I would purchase a different product.

The technology is top notch, it just the ANT+ keeps losing its connection for every workout (or new workout). My solution is to remove and put back the battery and it works again. Is there a way I don't need to do this often? Further, the cadence crank magnet needs an uplift remedy since it is quite far from the main device, but I found a solution to it. Hope this last even used outdoors!

Since I have had the device it has not synced to my smart phone I have tried everything and it won’t sync. I also had trouble getting it to work with the cadence tracker. The instructions don’t tell you about synchronization to any device I had to go on line
